I am using PDF Converter which allows you to make any we page into a PDF and lets you open into other programs i.e. dropbox, annotate, lifeforms etc... No merging of files. Can do on desktop I too have full version of Acrobat. Hopefully an iPad is soon in the making.

I have found a way to merge PDFs on the iPad, but it is a bit cumbersome. The app is called "PDF Forms" and it has an edit button where you can add one page at a time, so then you have to copy each page you want to add to the document. I think I'll try the Save2PDF app instead. Thanks for the info.....R
